摘要： Disclosed are metal nitride photoctalyst particles and/or metal oxynitride photocatalyst particles having high dispersibility. The metal nitride photoctalyst particles and/or metal oxynitride photocatalyst particles having high dispersibility can be obtained by containing metal nitride photoctalyst particles and/or metal oxynitride photocatalyst particles, which are capable of splitting water under visible light irradiation, and a phosphoric acid polymer that is adsorbed on the surface of the particles. Further, because these particles have high photocatalytic activity under visible light irradiation, splitting water by using these particles can generate hydrogen and/or oxygen with high efficiency.

摘要： Disclosed is a process for producing a sanitary ware. The sanitary ware includes a glaze layer and a photocatalyst layer provided on the glaze layer. The photocatalyst layer is an oxide film including a co-fired product of a precursor of titanium oxide and a precursor of zirconium oxide and contains 65 to 85% by mass of titanium oxide and 15 to 35% by mass of zirconium oxide. The process includes the steps of applying a solution containing at least a precursor of titanium oxide and a precursor of zirconium oxide on a surface of a sanitary ware free from a photocalyst layer, and then firing the coating to form a photocatalyst layer.
